This is probably a 1e vs 3e thing, but these cantrips are way too strong for my idea of cantrips. They'll serve as inspiration for creating some, so I'll still enjoy it, but they seem more like 1st and 2nd level spells to me.

These 100 Cantrips are a nice combination of funny and quirky spells and some fairly legitimate low-level spells you could take advantage of if so inclined. The spells are limited enough that they fit perfectly in the cantrip level, but they're also just desirable enough over the regular cantrips that players might actually be interested in them (and the special conditions that may be needed to acquire them). For the price there is a lot of content in this book. If you're a spellcaster or DMing for a pathfinder spellcaster, and you're more about the verisimilitudinous flavor and story than just raw power at all circumstances, this one's for you.
